So I have just come across this issue.
I am using the JQuery UI to have a datepicker which "maps" to a readonly textbox:
$(document).ready(function ()
{
var dateFormatStr = 'yy/mm/dd';
$('#DateOfBirth').datepicker({
dateFormat: dateFormatStr,
minDate: '-100Y',
maxDate: '-18Y',
changeMonth: true,
changeYear: true
});
$('#DateOfBirth').attr('readonly', 'readonly');
});
And in the View, this is what I am doing to bind it:
#Html.LabelFor(m => m.DateOfBirth)
#Html.EditorFor(m => m.DateOfBirth, new { #readonly = "readonly" })
This works fine in IE.
In Chrome however, not so much. It gives its own definition of the date picker control and you can see the jquery control behind it! And when you try to set the value, it fails to do so.
is there a reason why chrome is acting weird? I am guessing this is because the EditorFor is binding the DateOfBirth property which is of type DateTime.
Is there a way to stop this behaviour? I believe I had issues when I was using a TextBoxFor instead and had to use the EditorFor.
Many thanks
I don't see any Id with your EditorFor statement.
#Html.EditorFor(m => m.DateOfBirth, new { id="DateOfBirth", #readonly = "readonly" })
Don't know if that's the issue, I worked on the datepicker control yesterday and I had no issues. Unfortunately, I can't make much sense of what you describe as weird behaviour in Chrome.

I have an ASP.NET MVC web app and trying to use Bootstrap 3 Datepicker for my "month/year" field like the one in demo here:
https://eonasdan.github.io/bootstrap-datetimepicker/#min-view-mode
In that demo, it only allows users to select "year" and "month". Not "days". I want the same functionality in my app. However, in my app, it works the same on first click but on succeeding clicks it shows the "days" selection view. Setting the viewMode to 'years' doesn't fix the problem.
My model is as follows:
public class FilterViewModel
{
public DateTime? StartMonthYear { get; set; }
...
My view is as follows:
<div class="col-sm-3">
#Html.TextBoxFor(model => model.StartMonthYear, new { #class = "month-picker" })
...
<script type="text/javascript">
$(function () {
$('.month-picker').datetimepicker({
viewMode: 'months',
format: 'MM/YYYY',
useCurrent: false
});
});
</script>
The problem is that viewMode only sets the initial view. However, it seems this particular library doesn't provide any way to actually restrict which views are available.
There's an alternate libary that I personally use, which does give you the ability. It's virtually a drop-in replacement, so you shouldn't have to change much to switch over. However, importantly, it provides minView/maxView options you can utilize:
$(function () {
$('.month-picker').datetimepicker({
startView: 'month',
minView: 'month',
format: 'mm/yyyy'
});
});
As you can see there's a few minor differences:
viewMode becomes startView. The view names are also singular month vs. months.
The formatting string is more similar to C# formatting, so you'd use lowercase mm and yyyy.
The default for this library is to use the current date/time, so there's no need for a separate useCurrent option. If you want to specify a different start date/time, you'd use initialDate.
I found a work around which works pretty well:
$(function () {
$('.month-picker').datetimepicker({
viewMode: 'months',
format: 'MM/YYYY',
useCurrent: false
});
$('.month-picker').on("dp.show", function (e) {
$(e.target).data("DateTimePicker").viewMode("months");
})
});
This is based on a reply found here.
This was a bug in the library and solved. I faced same problem and solved by simply downloading latest version.
I tried setting the disableTouchKeyboard option but it did nothing -- at least on iOS/Safari. The options I was specifically using were:
$(".datepicker").datepicker({
autoclose: true,
disableTouchKeyboard: true,
format: 'm/d/yyyy',
startDate: '01/01/1900',
todayBtn: 'linked',
todayHighlight: true,
});
Anyone know what the best way to do this is?
If you are using Bootstrap3 Datepicker: https://eonasdan.github.io/bootstrap-datetimepicker
Just add this property to the input: readonly="readonly"
and this property to options when instantiate the library.
$('#datetimepicker1').datetimepicker({
useCurrent: false,
daysOfWeekDisabled: [0, 6],
format: 'DD-MM-YYYY',
ignoreReadonly: true <------ this property
});
Tested on Safari iPhone and Chrome / Native browser Android.
This is how I've accomplished this but I'd love to know if there are better ways.
Using the same options in the question, I then also made the HTML text box readonly by doing this in my HTML:
#Html.EditorFor(model => model.Date, new { htmlAttributes = new {
#class = "form-control datepicker", #readonly = "true",
}})
This seems to work as JavaScript can still change the value of the field. However, it does make the background of the text box gray (i.e., disabled) and it changes the mouse pointer to the crossed circle icon (not-allowed) which is not desired. To get around that I did this added an inline style:
#Html.EditorFor(model => model.Date, new { htmlAttributes = new {
#class = "form-control datepicker", #readonly = "true",
style = "cursor: default; background-color: #fff"
}})
I tried to override the cursor and background-color in CSS (using !important) but that didn't seem to work in Internet Explorer.
This isn't pretty but it works for me. Still need to see how I could do this in a more robust way (e.g., no hard coding the background color, not having to specify this on all of my date fields, etc.). If anyone knows a better way, I'd very much appreciate it.
I have/had a similar problem like this.
I use a input field type=text where i bind a jQuery datepicker to it. When I select the input field on my mobile (android chrome) I get the datepicker and the keyboard of the phone.
After searching StackOverflow I found some solutions about setting the input field on readonly or disabling the field. The problem with this is when you disable the field it will not be submitted, and when read-only is set my jQuery validator skips the field. So I needed a different solution.
I have now fixed it by letting the datepicker set the field on read only before opening the picker, and removing the readonly when the picker is closed. I have tested it so far on mobile android (chrome and I.E) and i dont get the native keyboard. iphone/ipad is not tested yet but maybe other can check it.
The code is:
$(this).datepicker({
beforeShow: function(input, obj){$(input).prop('readonly', 'readonly');},
onClose: function () {$(this).prop('readonly', false);}});
Just also add attribute readonly in datepicker.
$(".datepicker").datepicker({
format: "dd-M-yyyy",
autoclose: true,
disableTouchKeyboard: true,
Readonly: true
}).attr("readonly", "readonly");
This is an old question but I thought I should share my solution since this question shows up in Google search. If you make the input type a button the keyboard will not show up and you can style the button to look like a text input field if you really need to.
<input type="button" style="background-color:white;border:1px solid #DDD;padding:5px;cursor:text;" value="Enter a Date" id="datepicker">
This quick block of Javascript will allow you to disable keyboard input within Date fields. This snippet is helpful if you need to avoid the virtual keyboard from appearing within the datepicker.
<script type="text/javascript">
jQuery(function() {
jQuery( ".datepicker" ).datepicker({ }).attr('readonly','readonly');
});
</script>
I have a mobile datepicker that works except for its event functions, which are not called. What is the problem?
<script type="text/javascript">
$("#calendar").datepicker({
onSelect: function () { alert('1'); },
beforeShow: function () { alert('2'); },
beforeShowDay: function () { alert('3'); }
});
</script>
<div>
<input id="calendar" type="date"/>
</div>
Sorry before I haven't realised of the input type that's not correct. Datepicker usually works with input type text.
Date is a new input type on HTML5, you are using that calendar instead of jQuery datepicker, that's why events doesn't work.
Check this fiddle for your example.
I would suggest you to use datepicker because input=date isn't supported by many browsers and has less options.
I expect that in near future we could use HTML 5 features supported by all browsers and write less javascript code.
I'm working on some internationalization using jQueryUI. I have a DatePicker control on a form that is properly working in the French language.
When I select a date, for example August 15, 2012, the DatePicker will display 15 Aoû, 2012 as I would expect. My issue however, is that when the form is posted, the value of the DatePicker is posted as '15 Aoû, 2012' which now needs to be translated on the server before it can be saved properly.
My question is, is there a built-in way inside the jQueryUI DatePicker so that I can have it always post to the server in a consistent format, regardless of which language the control is being displayed in? If there isn't a built-in way, what options exist for achieving this?
I realize that I can change the dateformat to something like 08/15/2012 instead of using the textual representation, however this isn't what I want to do.
There's 2 configuration options for that: altField and altFormat. http://api.jqueryui.com/datepicker/#option-altField
If you specify an altField, that field will be updated too, and will have the altFormat.
Normally you will want make the altField a hidden field, soyou can ignore the regular field and send to db the altField.
As you'll have noticed, supplying a dateFormat works well for newly entered dates, but it does not alter the value attribute which was already supplied to the date input field. It took me some time and I'm not sure whether this solution is ideal, but here's my situation explained and the code which solves it. Might help others with the same problem in the future. In my example I'm using dd/MM/yyyy as the display format.
The page contains any number of date input fields, which may or may not already have a value attribute supplied in the format yyyy-MM-dd, as specified by W3C.
Some browsers will have their own input control to handle dates. At the time of writing, that is for instance Opera and Chrome. These should expect and store a date in the abovementioned format, while rendering them according to the client's regional settings. You probably do not want/need to create a jqueryui datepicker in these browsers.
Browsers which don't have a built-in control to handle date input fields will need the jqueryui datepicker along with an 'alt', invisible field.
The invisible, alt input field with the yyyy-MM-dd format must have the original name and a unique id in order for forms logic to keep working.
Finally, the yyyy-MM-dd value of the display input field must be parsed and replaced with its desired counterpart.
So, here's the code, using Modernizr to detect whether or not the client is able to natively render date input fields.
if (!Modernizr.inputtypes.date) {
$('input[type=date]').each(function (index, element) {
/* Create a hidden clone, which will contain the actual value */
var clone = $(this).clone();
clone.insertAfter(this);
clone.hide();
/* Rename the original field, used to contain the display value */
$(this).attr('id', $(this).attr('id') + '-display');
$(this).attr('name', $(this).attr('name') + '-display');
/* Create the datepicker with the desired display format and alt field */
$(this).datepicker({ dateFormat: "dd/mm/yy", altField: "#" + clone.attr("id"), altFormat: "yy-mm-dd" });
/* Finally, parse the value and change it to the display format */
if ($(this).attr('value')) {
var date = $.datepicker.parseDate("yy-mm-dd", $(this).attr('value'));
$(this).attr('value', $.datepicker.formatDate("dd/mm/yy", date));
}
});
}
<input type="text" name='fieldName' id="datepicker" value="" style="width: 100px;" />
<script type="text/javascript">
$( "#datepicker" ).datepicker( "option", "dateFormat", 'dd/mm/yy' );
$( "#datepicker" ).datepicker();
</script>
It appears someone else had this question or a similar one prior to yours.
If you read this stackoverflow answer, the author was trying to show the date in one format and pass the data to MySQL in another format.
The prior answer in that link gets you set up to access the selected value as a variable. Now all you need is to wire in a parseDate to your selected date variable.
<script type="text/javascript">
$('#cal').datepicker({
dateFormat: 'dd M yy',
onSelect: function(dateText, inst) {
var dateAsString = dateText; //the first parameter of this function
var newDateFormat = $.datepicker.parseDate('dd-mm-yyyy', dateAsString);
}
});
</script>
Check the parseDate link for settings and formatting.
Hope this helps!
Basically, you should not re-format the date. Instead, you should read JavaScript's Date object from Datepicker, via getDate() method. Then, you need to pass it to server.
The question is how. Basically, what you want is some common format. If you use JSON the answer is very simple, just put date object and JSON's stringify() function will automatically format it to ISO8601.
As you may see from Wikipedia, ISO8601 was designed to interchange date and time reliably, therefore that's what you should use.
It might be helpful to know that modern web browsers support Date object's toISOString() method.
As #Pawel-Dyda mentioned,
There's a
getDate() method
var currentDate = $( ".selector" ).datepicker( "getDate" );
Here's an example of what it returns: Wed Jan 20 2016 00:00:00 GMT+0300.
You can parse it in Javascript, PHP, in SQL or whatever.
MySQL parsing examlple:
select str_to_date('Wed Jan 20 2016 00:00:00 GMT+0300','%a %b %d %Y %H:%i:%s');
Returns:
2016-01-20 00:00:00
Solution working for ASP.NET
#using (Html.BeginForm("ActionName", "ControllerName"))
{
#Html.HiddenFor(m => m.DateFrom)
#Html.HiddenFor(m => m.DateTo)
<div class="form-group">
#Html.LabelFor(m => m.DateFrom)
<input id="datepicker-date-from" type="text" class="form-control datepicker" value="#Model.DateFrom.Date.ToString("dd.MM.yyyy")"/>
</div>
<div class="form-group">
#Html.LabelFor(m => m.DateTo)
<input id="datepicker-date-to" type="text" class="form-control datepicker" value="#Model.DateTo.Date.ToString("dd.MM.yyyy")" />
</div>
<input type="submit" class="btn btn-sn btn-primary" value="Download" />
}
#section scripts {
<script type="text/javascript">
$(function () {
$("#datepicker-date-from").datepicker(
{
dateFormat: "dd.mm.yy",
altField: #Html.IdFor(m => m.DateFrom),
altFormat: "yy-mm-dd"
});
$("#datepicker-date-to").datepicker(
{
dateFormat: "dd.mm.yy",
altField: #Html.IdFor(m => m.DateTo),
altFormat: "yy-mm-dd"
});
});
</script>
}
I have a very simple html page with the following javascript in it
$(function() {
$( "#datepicker" ).datepicker({
changeMonth: true,
changeYear: true
});
$( "#datepicker" ).datepicker( "option", "dateFormat", "yy-mm-dd" );
});
Then I have the input target element
<input id="datepicker" type="text" class="boxtpl" name="${field.name}" value="${release?.startDate}">
and I see the html of the input from viewing source is valid...
<input id="datepicker" type="text" class="boxtpl" name="release.startDate" value="2012-02-07">
so when I do the GET request to get this page, my date ONLY renders if I delete that last line in the javascript that sets the format WHICH is very important as that is the format I have playframework configured for!!!!! If I don't set the format, the POST then breaks because formats don't match :(
Why is setting the format of datepicker clearing out my date????
I can try scripting more to set it manually though I tried calling the api to set it and that DID NOT work so it might not work doing raw javascript set either...not sure yet. anyone know why this occurs or better yet how to fix it???
thanks,
Dean
Not sure if it's a bug in jquery ui, but it seems that setting the format effectively deletes the default value. You can fix this with a chained
.datepicker("setDate", datepicker_default_val );
However, what I did in my web app was define a CSS class ".datepicker" then writing this code snippet provide date pickers to any with that class.
$( ".datepicker" ).each( function(index){
var datepicker_default_val = $(this).val();
$( this ).datepicker({numberOfMonths: 3, showButtonPanel: true});
$( this ).datepicker( "option", "dateFormat", 'yy-mm-dd' );
$( this ).datepicker("setDate", datepicker_default_val );
});
What this does is grabs every element with the tagged class, saves the default value to local var datepicker_default_val, sets the formatting, and then restores the value.
Little bit of a hack but put that in a $(document).ready(function(){ }); block and you should be good.
If the input field does not match the default dateFormat, it will simply delete it.
The option setting in the second line is too late then, after the first line it is already deleted.
Solution: Set the dateFormat in the first call:
$( "#datepicker" ).datepicker({
changeMonth: true,
changeYear: true,
dateFormat: "yy-mm-dd"
});
What do you mean by:
the POST then breaks because formats don't match
Also, I don't quite understand what you mean by your GET and POST requests? Do you mean the form methods? In such case you should amend your HTML code with the surrounding form tags and add a submit button so we can understand exactly what you want and try to reproduce the problem.
Anyway, see if this is what you want : http://jsfiddle.net/DAMEj/
Actually I just included the Jquery UI library in addition to their CSS for a full test of your code.
Besides, I don't get the purpose of these attributes name="${field.name}" value="${release?.startDate}", could you clarify?
And finally, what is it exactly that doesn't work for you?
EDIT:
So according to my last comment about the default date display, please check this out http://jsfiddle.net/sidou/ZUrPj/ and see if it fits your needs.
Happy JS fiddling ;)
If the input value is not parseable by jQuery, it will indeed delete the value from the input field (and even from the altField, if you set one).
For example, this might happen when using different locales. If you set the datepicker dateFormat to 'dd MM yy' and use French localisation, it will parse "10 Mars 2012", however a value of "10 March 2012" will get deleted.
In my case, i found than the JQuery was inyected by a "formoid" solution, soo, i just replace the function where the data was reinjected, adding the line
"value": date.attr("value")
I mixed with the Shaun answer too:
jQuery(".formoid-flat-blue").find('input[type=date]').each(function(){
var date = $(this);
var datepicker_default_val = $(this).val();
var text = $('<input type="text">');
text.get(0).className = date.get(0).className;
text.attr({
"name": date.attr("name"),
"placeholder": date.attr("placeholder"),
"required": date.attr("required"),
"value": date.attr("value")
});
date.replaceWith(text);
text.datepicker({
format: _dateFormat || date.attr("data-format") || 'yyyy-mm-dd'
});
if (datepicker_default_val) {
text.datepicker({
setDate: datepicker_default_val
});
}
});
